Mobile phones are not only a ubiquitous social accessory, but rapid technology advances have transformed them into feature-rich, Internet-enabled mobile PCs---a role once reserved for touchscreen-based personal digital assistants (PDAs). Although the most widespread phone styles in circulation feature the classic combination of numeric keypad and non-touchscreen display, larger touchscreen devices are gaining ground, as indicated by the fervor surrounding new devices such as Apple's iPhone and LG's Prada phone. Yet as devices evolve, users will remain constrained by the limits of their own visual, physical, and mental resources. My research has focused on the specific limitation that mobile users often have only one hand available to operate a device, which can be especially problematic for touchscreen-based devices, since they are frequently designed for two-handed stylus operation. Considering the growing volumes of data that small devices can now store and connect to, as well as the expanding cultural role of mobile phones, improving usability in mobile computing has potentially enormous implications for user productivity, satisfaction and even safety.whose directional hardware is placed at the bottom of the device, it is clear that
